My hands have been killing me all day and I couldn't figure out why. Jenna just pointed out that I spent 45 minutes yesterday with and without the proper tool trying to remove her factory installed oil filter on her CX-9. Some robot, no, some super advanced terminator robot at Mazda must have screwed this thing on because the tool designed specifically for making removal of the oil filter easy still needed me to use all my strength to the point of shaking uncontrollably just to get it to budge. Next oil change should go smoother but I'm definitely gonna need a friend and some beers to help out just in case.
